I need your help guys and girls .
I´m messing around with Win RT to make some apps....well, I like to use the roaming folder to store some textfiles. So, I´ve read that it (the roaming folder) can only be 100kb at all?! this is not much, and some textfiles will be bigger then that? what should I do, or I´m missinformed?

Typically it is not much... but it is not intended to store data apart from application settings and things like that. The idea is that if you application runs with the same accounts on different devices it will have the same state, properties etc.

If your application needs to store some data you should consider using Azure (or another cloud service) to store that data, that will remove all the size constraints of the roaming folder.
